METHOD OF FOLDING THE EDGES OF COLLARS FOR PERSONAL WEAR.

Application filed August To all w ham it may concern:

Be it known that I, ALEXANDER F. ZAKR- znwsnr, a citizen of the United States, and a resident of Green Island, county of Albany, and State of New York, have invented certain new and useful Improvements in Methods of Folding the Edges of Collars for Personal Wear, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to avoid exposing the raw edge of the cut material at the extreme edge of a collar; to add to the resistance to tearing of the material forming an inner corner of an article such as the collars worn by men; and to produce a more finished and sightly article of the character mentioned.

Drawings Figure 1 is a top view of a fragment of one of the plies of material from which collars are constructed;

Figure 2 is a schematic view showing in section a fragment of the material shown in Figure 1, the section being taken as. ,0n the line 2-2 in Figure 1, and in conjunction therewith a fragment of the die plate and of the folder blade for overturning the material of the collar at the inner corner of the collar, or where the skirt of the collar joins the neckband;

Figure 3 is a similar view showing the folder blade at the moment of engaging the upstanding edge of the material, to cut and fold the same.

I-Ieretofore in the manufacture of collars for personal wear it has been the custom to fold the edge of the collar at the inner corners thereof. The overturned edge of the material under these conditions bunches atthe corners and the material being nonresilient, and non-stretchable, it has refused to be thus folded. To accommodate the material, to the conditions, the material has been cut at the corners and to the outer edge of the pattern or collar. The result of this has beenthat at the outer edge a small fraction of the material has been presented in its raw or unfinished state. This has been accentuated in the laundry by pulling one part or the other at the opposite sides of the corners with the result that the unprotected or unhemmed edge has given way and the material has been torn. To avoid this is the principal object of the present inven- 1, 1925. Serial No. 47,395.

tion, and to this end the blanks 8, from which the collar is to be formed, are placed in a suitable machine for overturning the edges 9. Machines of this character have a die platen 10. The platen 10 has the peripheral shape of the collar to be made. rial of the blanks 8 is forced down in a die socket by the platen 10. While the platen 10 is held firmly in position folders such as indicated by the numeral 11 are moved over the platen and the edges 9. The edge 9 at the corners ofthe collar band and collar skirt is overturned by the folder 11. The folder 11 at this corner, however, has a sharpened knife blade 12. The folders 11 have preferably upwardly inclined surfaces 13. The platen 10 has a downwardly inclined surface 1 1, the two surfaces being thus constructed override each other and the advanced end of the knife 12 first engages the material forming the edge 9 above the holding edge of the platen. As the blades 12 advance over the platen 10 and the interposed material, the material is stretched or drawn hard over the cutting edge of the blades 12. The result of this is that the material is cut from the point indicated by the numeral 15 in Figure l to the inner margin of the edge 9, thus forming a cut-away portion 16 which relieves the edge 9 at the opposite sides thereof from the pulling strain of the cloth. It will be noted however that the narrow width 17 of the material extends between the inner corner of the cut portion of the edge 9 and the inner corner of the collar member.

It will be understood that each collar is constructed from two collar members of the character shown in Figure 1 of the drawings, or, in other words, of two plies of the finishing material. If a filling material is employed to stiffen or give body to the collar it is placed between the collar members. But it will be observed that when the edges 9 and the narrow width 17 thereof are overlaid, and the collar members have been stitched there will be found to be no raw edge or weak end portion at the inner corner of the collar structure.

It will be understood that other devices may be employed for cutting the edge 9 to form the inner corners of the collar, but by cutting the material as described in the operation of turning the material certain accuracy'in the shaping and placing of the The matematerial is obtained which would otherwise prove difficult if not impossible.

Claims:

1. A method of folding fabric at the edge of a reentrant angle therein comprising the preliminary folding over of a narrow section of the fabric at said angle, and subsequently slitting the remainder of the edge fold in a line bisecting said angle.

2. A method of folding fabric at the edge of a reentrant angle formed therein comprising turning up the edge of the fabric along the sides and at the point of the angle, folding down the fabric along the sides and at the point of the angle in a strip relatively narrow to the upstanding portion, subsequently slitting the upstanding portion of the fabric in a line bisecting said angle and subsequently pressing down the remainder of the material in the plane 20 of said folded narrow section.
